How does norethindrone birth control pill work?

• Norethindrone is a progestin, and progestins prevent pregnancy by inhibiting ovulation (release of the egg), making it more difficult for sperm to penetrate the uterine mucus that surrounds the egg, and therefore, for fertilization to take place. Progestins also change the uterine lining to prevent the fertilized egg from implanting in the uterus.
